- 4. Dell World UserForum How does Mac imaging work? • Macintosh computers use bootstrap protocol (bootp) and netboot environments to capture/deploy system images independent of client hardware. • A netboot environment is created from OS X installation media or installer app from the App Store. Only one netboot environment is needed to netboot different Mac models.
- 5. Dell World UserForum Netboot, Subnets, and You Netboot across subnets requires bootpd relays. Various methods include: • RSA on individual subnets • Bless command • IP-helpers at the routing level
- 6. Dell World UserForum Customizing Mac Deployments Pre and Postinstall tasks operate in a similar fashion compared to Windows. HDD partition tasks, software deployment, and OS X customization shell scripts are some of the supported features. Unlike Windows, there is no sysprep tool for Macs but there are a few best practices for preparing a Mac gold master system image.
- 7. Dell World UserForum Netboot Basics
- 8. Dell World UserForum Netboot Environment • A netboot image is a hardware independent operating system that allows hard drive capture and deployment over the network. One netboot environment contains drivers for multiple Intel Mac hardware configurations. • The netboot environment also supports network connectivity to the K2000’s Samba shares along with network mapping capabilities. Additionally, KACE has provided the OS X troubleshooting tools for use in the netboot environment. • Build the netboot environment on a Mac running latest version of OS X that will be deployed. It is also advised to build the netboot environment on the newest Mac hardware available for certain feature support, such as Thunderbolt 2.

- 26. Dell World UserForum K-Image vs. Native Image (DMG) • K-Image: De-duplicates file structure resulting in smaller image footprints on the K2000 HDD. • DMG: Fast solution with no data deduplication, resulting in speedy deployments which utilize more space on the K2000 HDD.

- 28. Dell World UserForum Best Practices
- 29. Dell World UserForum Best Practices Tasks Best Practices • Use postinstall tasks for software that is updated regularly (flash, reader, etc.) and utilize the K1000 for updates. • Be descriptive in your naming of captured images. • Be consistent with naming Postinstall tasks, like adding "App-" or "Script-" as a prefix to help keep tasks organized. Netboot Best Practices • Build from newest hardware available • Build from most up to date host OS with matching Source Media • Test Netboot on different Model Macs on different network segments
